    The present study had as its guiding themes environmental education, environmental communication, watershed management and the use of evaluation indicators. Themes that were thought based on a systemic and integrated vision of human beings with the environment and with the other living beings on the planet. The main objective of this study was to investigate concepts, practices and approaches to environmental communication and environmental education in river basins, aiming to establish specific instruments, criteria and indicators for the analysis of projects and activities in watersheds. To support the reflections made in the study, a systemic and complex approach was adopted. In order to achieve the proposed objectives, bibliographic research techniques (systematic bibliographic review), exploratory and applied research (questionnaires with members of river basin committees and experts from related areas) were used, which allowed the collection of data and information, analyzed through bibliometric analysis techniques and the 3S validation methodology. How the main results of this thesis were generated: an instrument for evaluating proposals for environmental education projects within the scope of river basin committees; a list of indicators for evaluating environmental education actions and activities in watershed; a framework of action guidelines for environmental education activities. It is concluded that there should be a greater integration between the themes of environmental communication and environmental education, in order to increase the scope of actions and activities that can be carried out in watersheds, mobilizing and involving society, generating behaviors beneficial to the environment , in addition to understanding the current socio-environmental problems present in society and contributing to the creation of a new paradigm of the relationship between human beings and the environment.

    SILVA, Josefa Erica Monteiro da. Paths of the local knowledge to Agroecology: choices and practice changes at Settlings of Iperó’s Land Reform. 2021. Monograph. (Bachelor Degree in Biological) – Universidade Federal de São Carlos campus Sorocaba, Sorocaba, 2021. Agroecology emerges as a critical science to the hegemonic model, and proposes the multidimensionality of sustainability for the development of ecological agriculture. As a practice, it proposes innovative technologies, which are consistent with the peculiarities of different realities and respects the ecology of knowledge. In addition to that, it works as well as a socio-cultural and political movement, related to the demands of local people and communities that exist and resist daily. Ecological agriculture presupposes that, instead of fighting symptomatic factors and replacing chemical products with organic ones, as in organic agriculture for instance, there is a holistic view of the agroecosystem in order to deal with causal factors. The importance of the Agroecological Transition process lies in the resignification of the management of agroecosystems, moving away from the model based on the use of agrochemicals and transgenics to the construction of principles that aim at a healthier relationship with nature. In this context, the present work analyzes the role of local knowledge on choices and changes in agricultural practices throughout the history of the Ipanema and Horto Bela Vista (Iperó/SP) settlements, towards agroecological practices, in order to understand how it occurs the construction of knowledge, which factors influenced the choices of agricultural practices and the effect of the latter on the lives of farmers. For this matter, semi-structured interviews were carried out with the farming families involved in the Participatory Guarantee System (SPG) and, therefore, already practicing sustainable management (but not necessarily agroecological). Results pointed to a vast knowledge about agroecological and agricultural practices, such as agrobiodiversity, use of organic matter in the farms, intercropping and crop rotation, little use of machinery and ecological management of the soil. This knowledge is linked to the involvement of farmers in exchanges from the SPG, experiences in the field, transmission between generations and sociocultural awareness, but mainly in the horizontality and dialogue of knowledge between farmers, extension workers and the “Rede Agroecológica Sorocabana”, which contributes to the construction of agroecological knowledge, confidence and self-esteem of the settlers. Among the factors that influenced the agroecological transition are reports of intoxication due to the use of pesticides, socio-environmental awareness, consumer demand, financial motivation, access to knowledge, public policies and agroecological transition projects. As for the effects of these choices on the lives of farmers, there is an increase in the possibilities of disposal, quality of life, financial security and food sovereignty, based on an analysis that encompasses an ecological, socioeconomic, cultural, political and ethical view.

    Today, with the constant growth in the number of available digital content and ease of access to a huge amount of data, it is increasingly difficult to find relevant information. From this problem, recommender systems have emerged, analyzing user's behavior to issue personalized item recommendations. Currently, most companies have some form of content recommendation on their channels or services. Even so, many problems in the area are not properly solved, such as the high dimensionality and sparsity that the commonly adopted representation model has. Methods have been proposed to solve these problems, representing items and users as dense vectors in a space of reduced dimensionality. One of the most recent techniques in the literature is the use of embeddings-based models, i. e., distributed vector representations generated through artificial neural networks. Many of the latest advances in the area have shown promising results when compared to other already consolidated methods, but the vast majority of proposals suggest the execution of complex neural architectures or the use of content data, which often may not be available int the scenario of the application. In this dissertation, we extend the studies in the field of embeddings-based recommender systems. Through a comprehensive literature review, a new model for generating distributed representation is proposed, with the key points of being computationally efficient and requiring only implicit feedback from users to be trained. The results obtained in extrinsic and intrinsic evaluations, indicate that the model is promising for scenarios where there is need for computationally efficient models, achieving competitive results with state-of-the-art methods that demand greater computational power.

    Waste electrical and electronic equipment (WEEE) is among the fastest growing types of solid waste in the world. In addition, this is a complex waste stream when it comes to recycling, due to the large variety of valuable materials and toxic elements present in plastics, metals, glass, ceramics, etc. In this context, the chemical analysis of electronic waste and issues involving the management of this matrix were discussed in this thesis: (1) initially, bibliometric resources were used to evaluate the different topics involving the handling of electronic waste and the evolution of world research; (2) as well, given the lack and difficulty of producing materials to ensure the traceability of measurements and validation of analytical methods, an electronic waste reference material was produced and evaluated following all standards established by ISO guides 30 - 35; (3) finally, different techniques of direct analysis such as laser-induced breakdown spectroscopy (LIBS), laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) and X-ray spectrometry (XRF) were used to develop analytical methods for elementary determination in printed circuit board (PCB) and liquid crystal display (LCD) samples. Bibliometrics proved to be an efficient resource for analyzing past research topics, emerging research hotspots and assess the current status of electronic waste research. Studies involving the analysis of critical elements (e.g. In, Pd, rare earths) and the development of reference materials for e-waste have been identified as gaps in the current literature, which are addressed and discussed in this thesis. New univariate (multi-energy calibration, MEC) and multivariate (data fusion using partial least squares regression, PLS) calibration strategies have been proposed for direct analysis of e-waste samples (i.e. PCB and LCD), through elemental analysis and chemical mapping within the sample surfaces. Considering the applicability, advantages and limitations of each analytical technique used, combined with appropriate chemometric tools, it was possible to propose new methods for analyzing complex matrices such as e-waste, which make it possible to minimize or even eliminate possible interferences, with analytical performance similar or superior to those existing traditional alternatives.

    In this work we propose a new survival model called the Bell-Inverse Gaussian cure rate. We consider different activation schemes in which the number of factors $M$ has the Bell distribution and the time of occurrence of an event follows the Inverse Gaussian model. The parameters are estimated by the classical and Bayesian methods. In a simulation study, we investigate the mean estimates, biases, mean squared errors and coverage probabilities in different activation schemes. In order to detect possible influential or extreme observations that can cause distortions on the results of the analysis we use the Bayesian method of influence analysis of case deletion based on $\psi$-divergence. Finally, we show the applicability of the proposed model to a real dataset.

    Background: Sepsis is a serious organ dysfunction that leads to endothelial damage. Passive mobilization (PM) results in increased blood flow and shear stress. Increased vascular diameter has been observed as a response to physical exercise, although it has not yet been explored in patients with sepsis. Objective: To explore patterns of vascular response to PM and seek associations with the clinical profile, cardiac autonomic modulation (CAM) and arterial stiffness in patients with sepsis. Methodology: Cross-sectional, single-arm study. Were included 32 patients diagnosed with sepsis. The PM protocol consisted of dorsiflexion / plantar flexion movements, knee / hips flexion / extension, wrists and elbows and shoulder flexion in 3x10 repetitions, with an interval of 15 seconds between sets and 30 seconds between joints (totaling = 12 minutes). Vascular response was assessed by flow-mediated dilation (FMD) using brachial artery ultrasound, with the FMD being obtained before and after PM. The Δ PM (to assess the response pattern) and SS (shear stress) were also calculated. Arterial stiffness was assessed by Sphygmocor®️, by analyzing the morphology and pulse wave velocity. The MAC was assessed by analyzing heart rate variability in the time domain (mean HR and RMSSD), frequency (LF, HF) and non-linear (ApEn, SampEn, DFA). Results: Different vascular responses were observed: 1. Increased vascular diameter (responders) (Δ% DMF = 11.89 ± 5.64) and 2. reduction in vascular diameter (non-responders) (Δ% DMF = -7.42 ± 6.44). Responders had a higher Alpha 2 index (p = 0.02). A positive association was identified between ΔFMD and Alpha 2 (r = 0.529; p = 0.03) and SampEn (r = 0.633; p <0.01) and a negative association between ΔFMD and LF (Hz) (r = -0.680; p <0.01) and IL-6 (r = -0.469; p = 0.037). Additionally, a negative association was observed between ΔSS and CRP (r = -0.427; p = 0.03). Conclusion: Patients with sepsis present different patterns of vascular reactivity in relation to passive mobilization. The increased vascular diameter pattern was associated with greater complexity of the autonomic nervous system and inversely related to sympathetic modulation and inflammatory profile.

    Sphenophorus levis (Curculionidae: Coleoptera) is one of the major pests of sugarcane crop in Brazil and presents cysteine proteases as main digestive enzymes. In this project, we report the characterization of Sl-CathL-CS, a variant of the main digestive cathepsin (Sl-CathL) of the insect S. levis that presents a serine residue instead of a cysteine in the catalytic site at position 138. In addition, a mutant enzyme, in which serine 138 was replaced by a cysteine residue was produced and named Sl-CathL-mutSC. Sl-CathL-CS did not show proteolytic capacity, but Sl-CathL-mutSC was able to hydrolyze milk proteins and the substrate Z-Phe-Arg-AMC (Vmax = 1017.6 ± 135.55 and Km = 10.766 mM). This mutant was inhibited by E-64 (Ki = 38.52 ± 1.2 μM), but not by PMSF, which is an inhibitor of serine proteases, and the static docking showed the difference of the active site of the two proteins. Interaction assay between them and the cystatin CaneCPI-1 revealed that Sl-CathL-CS has greater interaction with this cystatin, indicating that the protein can assist in the insect digestive process by interacting with the plant cystatins thus allowing the true proteases to work. Considering the importance of the cystatin/cysteine proteases interaction, Laboratory of Molecular Biology has dedicated itself to the study of sugarcane cystatins, being responsible for the identification and characterization of six of them (CaneCPI-1 to CaneCPI-6). Among them, CaneCPI-5 presented high inhibitory capability against Sl-CathL, which is the main digestive enzyme of the insect, besides inhibiting other cysteine cathepsins. Interestingly, this cystatin can protect tooth enamel against acid erosion and cavities. For this reason, there is a need to upscale its production to fulfill potential industrial demand. In this work, CaneCPI-5 was produced in a plant-based system by cell lysates (cell-free systems) of Nicotiana tabacum cv Bright Yellow cells (BY-2 cells), transient expression in leaves of Nicotiana benthamiana and stable expression in BY-2 cells. It was possible to obtain 25 μg of purified protein per gram of infiltrated leaf and the protein showed similar inhibition (Ki = 10 nM) to that of CaneCPI-5 produced in bacteria. CaneCPI-5 was also produced in transgenic sugarcane vacuoles and was purified from its juice, yielding 200 ug per mL, which, in the field, would allow the production of up to 15.3 kg of protein per hectare of sugarcane. The transgenic sugarcane events had their resistance against the attack of S. levis larvae assessed, however the transgenic clones failed to express the protein in the juice after propagation in the greenhouse, which may have occurred by gene silencing. This may have been responsible for them not showing increased resistance.

    This study is part of the research line “Management of Care, Work and Education in Health” of the Postgraduate Program in Clinical Management at the Federal University of São Carlos (UFSCar), São Carlos-Brazil. Because of the intrinsic relationship between this Professional Masters’ project with health policies, this research investigated the knowledge and opinions of dentists working in Primary Care in the city of São Carlos on Atraumatic Restorative Treatment (ART) and the receptivity of these professionals to use the strategy in the public service. This is an exploratory, observational, cross-sectional, and institutional study, based on a study population of 50 dentists, which corresponds to the total number of professionals working in primary care in the municipal network, 41 of whom answered the questionnaire. The variables herein investigated involved the following: general characteristics of the participants, their knowledge, suggestions, and materials used in the ART technique; intended use and actual use of ART in the public service; and potential barriers of not applying the ART technique, such as: operator’s opinion; operator’s opinion about the patient’s perception; workload; material support; clinical expertise for ART; supervision of the oral health service; oral health assistant. Descriptive analyses were performed on the following data: characterization of the participating professionals, frequency of responses, and comparison with their expected response, as well as associations between the usage and intended use variables and other variables of all blocks using the chi-square test or Fisher's Exact Test (significance value < 0.05). Regarding the general characteristics of the participants, 80.49% graduated before 1995 and 58.54% had more than 25 years of experience in public service. Regarding knowledge of the researched individuals, their suggestions, and the material used in the ART technique, it was noteworthy that 46.34% of the individuals understood it to be a type of provisional intervention or the same as the suitability of the environment; when analyzing the uses and intended application of the ART technique, 90.24% believed this strategy interrupts the process of caries and prevents the loss of the dental element and 70.73% agreed that it should be widely used in Primary Care. Concerning the barriers to not applying the technique, 46.34% of the participants considered it to be an inferior treatment when compared to other restorative techniques and only 39.02% indicated that the manager understands the concept of ART. In view of these findings and given the need for non-invasive procedures in oral health care services due to the arrival of the COVID-19 pandemic, a proposal for ART training for dentists in primary care in São Carlos-SP will be developed in collaboration with the Oral Health Coordination of the city administration.

    The evolution of the concentration of different gases in the Earth's atmosphere is a worrying phenomenon, because the ongoing process of global warming is not explained only by natural causes and is largely due to greenhouse gas emissions (GHGs), which are aggravated by human activities, in particular transport-related emissions. Thus, this study aims to assess the structural changes in the Brazilian economy (level of intensity, technology, structure of final demand, volume of final demand, size of the population, among others) related to GHG emissions, from both an aggregate and sectoral point of view and, in this case, focusing on the transport sector, which is responsible for a large volume of GHGs emitted in Brazil. The methodology applied was the structural decomposition analysis (SDA) with an environmental approach, based on input-output matrices estimated for Brazil, between 2010 and 2017 and data from the Sistema de Estimativa de Emissões e Remoções de Gases de Efeito Estufa (SEEG). The results showed that Brazil showed an increase in its level of GHG emissions, fueled both by technological effects and by effects linked to final demand. Therefore, the intensity of emissions and changes in production technologies in economic sectors, combined with population growth and the level of final demand, have contributed to the increase in pollutant emissions in the country. From a sector perspective, the ‘Land Transport’ sector has been characterized as an intense pollutant, as it emits a high level of pollution per monetary unit produced and indirectly influences GHG emissions in other economic activities.

    Policies for the flexibility and legalization of Cannabis use in several countries has increased considerably in recent years and the use of drugs of abuse during pregnancy can affect the development of physiological systems including the respiratory control network, mainly due to the susceptibility of the prenatal period to external and pharmacological interventions resulting in possible consequences in the offspring’s postnatal life. Cannabis psychoactive compounds can act directly on the endocannabinoid system present in the Central Nervous System (CNS) already in the early stages of embryonic development, being an important element for structural and functional regulation of CNS maturation, including for the areas responsible for cardiorespiratory control. However, despite the increased consumption of this substance during pregnancy, knowledge about the influence of exogenous cannabinoids on the development of the respiratory system and the consequences on postnatal life is limited. The present study evaluated the possible effects of cannabinoid receptor (CB) agonist exposure during pregnancy on the respiratory control system of neonatal (P0, P6-7 and P12-13), juvenil (P27-28) and adult (P80-81) male and female rats through subcutaneous implantation of osmotic pumps in pregnant female rats at embryonic day 0 and delivered vehicle or agonist (WIN 55212-2, 0.5 mg/kg/day) for 21 days. WIN exposure interfered in a sex-specific maner with breathing regulation of offspring, thereby promoting a greater sensitivity to CO2 in neonatal, juvenile and adult males. An altered chemoreflex in response to hypoxia was observed in P0 and P6-7 newborn males. In females, prenatal treatment resulted only in a hyperventilation during hypercapnia at juvenile age and a reduced ventilatory response to CO2 and O2 at adulthood. In addition, brainstem neuroanatomical analysis showed an increase in the number of catecholaminergic neurons and CB1 receptor expression and alteration of tissue respiration in early stages of males. A significant reduction in lung compliance was also observed in treated juvenile males. Finally, cardiovascular changes were also observed for male and female animals in adulthood due to prenatal WIN exposure. These findings demonstrate that exposure to the cannabinoid receptor agonist during pregnancy results in prolonged and sex-dependent consequences for the cardiorespiratory control system.

    Questions about psychic suffering are often associated with the university environment, and they represent challenges that require institutional policies to be sought. It is crucial to understand how psychic suffering manifests in different university contexts, to know which are its actual dimensions and determinants. Through a critical perspective, knowledge about psychic suffering can allow the interpretation of the health-disease process of organizing social life, work, and social reproduction. This study intends to identify the prevalence of psychic suffering and its associations based on the understanding of social determination in health among undergraduate and graduate students at USP São Carlos, at one of its teaching units, the Institute of Mathematical and Computer Sciences (ICMC). The research was based on an exploratory epidemiological population, observational, cross-sectional, institutional studies with a critical analysis of 310 undergraduate students and 122 graduate students. The data collection was carried out electronically between September and November 2020, through a self-administered questionnaire composed of a socio-demographic inventory and on health issues and the instrumental Self-Reporting Questionnaire (SRQ-20), which signals the presence of psychological suffering by screening for Common Mental Disorders (CMDs). Data was exported to the RStudio program (R CORE TEAM, 2020) and the Stata program version 14 (College Station, Texas, USA) to analyze distributions and associations. Among undergraduate students, the results showed a general prevalence of CMDs was 72.9%. There was an association with family per capita income, income variation from the period before the pandemic caused by COVI-19 and the moment of research, being a cisgender woman, LGBTQIA+ sexual orientation, reporting difficulty in staying at the University, being followed up with a mental health professional and making use of psychiatric medication. In the adjusted analysis, we found an association and odds ratio between positive screening for CMDs and being a cisgender woman (OR = 2.69), reporting difficulties in staying at the University (OR = 3.45) and being monitored by a mental health professional (OR = 3.74). For graduate students, the general prevalence of CMDs was 72.1%. We found an association with family per capita income, reporting difficulty staying at the University, being monitored by a Mental Health professional, and using psychiatric medication. In the adjusted analysis, we found an association and odds ratio between positive screening for CMDs and difficulty staying at the University (OR = 10.3). The prevalence of psychic suffering was high in both groups. These findings can serve as the basis for the development and improvement of public policies for Student Assistance in the context of Collective Health and the Unified Health System. Among the recommendations is the strengthening of the national assistance policy student, with the expansion of coverage to graduate students, strengthening and creating actions and diversity policies that combat prejudice and discrimination at the national and local levels. It is necessary to consider the transformation of the university environment as well as beyond its limits, considering that what is lived at the university is also a reflection of life outside it.

    The definition of an efficient set of performance indicators can guide the organizations to reach its main strategics objectives. It is understood as an efficiente set, when the organization have a number of indicators that cover its process but in an adequate amount. In addition, such indicators can be used as a guide for the deployment of all tactical and operational actions that organizations perform. Methodologies based on continuous improvement use indicators for the measurement and control of leaner alternatives in its processes, among which, the logistical processes. In parallel, strategic deployment methodologies such as the Balanced Scorecard (BSC) assist in translating the organizations strategic objectives into their operations. The Lean Logistics is a derivation of lean manufacturing, which focuses on the logistics processes between supply chain agents as well as the internal logistics processes of organization. The focus of lean logistics is to oppose the seven wastes of lean philosophy, applied to logistics processes, as: Overprodutction, Waiting, Transportation, Motion, Defects, Inventory and over-processing. Relating the themes presented, this research proposes a model for the selection and definition of a set of indicadors or KPIs (key performance indicators), necessary for the measurement and control of seven wastes of lean logistics, prioritized by the organization’s strategy, based on the BSC four perspectives. This set of indicators, identified through a literature review, was grouped according to the seven wastes, and used later within a selection method. The use of DEMATEL and AHP decision support tools, helped to choose the main indicators, primarily through the waste in which they were grouped and after ranked considering the BSC’s perspectives as criteria. The research is done through a case study, carried out in a large company, in a moment of the implementation of lean philosophy. As a result, a model proposal was developed to assist the definition and prioritization of indicators, in addition to providing a list of indicators ranked to control the logistics processes, based on the seven wastes of lean logistics and the perspectives of the BSC. These indicators were sufficient to cover the 7 wastes according to the initial grouping. The solution suggested by the methodology considers a final set of seven indicators ranked according to the preference of decision makers in operational and strategic biases within the applied case study, considering the indicators based on financial perspectives as more applicable to support the strategies of the organization.

    Quinoa (Chenopodium quinoa) and amaranth (Amaranthus spp.) are pseudocereals with elevated nutritional and functional qualities. The first chapter presents a review of the literature on quinoa and amaranth, highlighting their morphological, agronomic, nutritional and socioeconomic aspects. In the second chapter, the objective was to identify the profile of consumers of quinoa and amaranth in addition to observing their consumption habits in relation to these foods. The data was collected through the application of an online questionnaire, which contained questions about the consumer's profile, the knowledge and consumption of quinoa and amaranth, the diversification of food and the preference and choice of packaging. In the third chapter, the objective was to evaluate the hydration kinetics of quinoa and amaranth grains, in order to observe the transfer of water mass to the grains. Tests were carried out at four temperatures (25, 50, 75 and 100 °C), monitoring the mass gain by water absorption and applying the Peleg model to the data obtained. It was concluded that quinoa and amaranth have great potential for composing functional diets, bringing benefits to the health of those who consume them, and that broader dissemination of these foods can contribute to their inclusion in the diet of more and more people.

    Francisco Clementino de San Tiago Dantas (1911-1964) was a jurist, politician and intellectual from Rio de Janeiro who played an important role in Brazilian public life between 1929 and 1964. His intellectual production and political action are deeply connected to the construction of the centralized national State in Brazil and to the country’s transition from agrarian to urban, industrial society. Similar to several other intellectuals of his generation, San Tiago Dantas began his trajectory linked to the Brazilian Integralist Action (a fascist inspired movement), converting to the democratic and developmental field after World War II and becoming a leader and an ideologist of the Brazilian Labor Party in the 1950s and 1960s. The objective of this thesis is to investigate Dantas social trajectory - highlighting his networks of relationships and attachment to groups - and his intellectual production - seeking to map his theoretical and political-ideological formulations - in the period from 1929 to 1964. In the research, I used published and unpublished texts by the author (books, speeches, manuscripts, interviews, transcripts of classes and courses), correspondence sent and received, memories and interviews of contemporary characters and newspaper and magazine reports. The analysis of this material allowed the identification of three political-ideological phases in the trajectory of San Tiago Dantas, described in this thesis: 1) catholic/ integralist (1929-1945); 2) non-nationalist developmentalist (1945-1955); 3) laborist/reformist developmentalist (1955-1964).

    Context: With the increasing presence of technology in daily life, it is crucial to guarantee the quality of software products, which can be reached by testing activity. However, testing is highly expensive, once it is responsible for, in most cases, more than half of the software development cost. Among the existing testing criteria, mutation testing is highlighted once it is capable of revealing specific faults in software. Although mutation testing is effective, test data generation and live mutants analysis make the activity unfeasible because it is still required considerable human intervention. Goals: Therefore, this paper aims at evaluating four automatic test data generators (EvoSuite, JTeXpert, Palus, and Randoop), focusing on mutation testing, by measuring adequacy, effectiveness and cost. The first three of these generators implement heuristics during test data generation and they are evaluated both individually and combined, using as baseline a randomic generator. Method: Such generators are compared by conducting an experiment with 33 software products implemented in Java. Adequacy is measured regarding statement coverage, effectiveness regarding mutation score and cost regarding the number of generated test cases. For each generator we generated 10 different test sets for each one of the 33 analysed programs, totaling 1320 distincts test sets. Results: Results show, when we analyze the generators individually, it is not possible to conclude there is a difference between them. However, when we combine the heuristic-based generators, it is possible to conclude there is significant improvement when compared to the randomic generator. Moreover, when we combine all generators, including the randomic one, we obtained improvments of 0,2% in statement coverage and 4% in effectiveness, but we also obtained a significant increase in cost. Conclusion: In general, we observe there is a complementary aspect between the three automatic test data generators and they should be combined to improve the quality of test sets regarding mutation score. However, even with such combination, there is still 25% of the generated mutants which remain alive, indicating there is still room for improvements on quality of the used generators.

    The search for barbados gooseberry (Pereskia aculeata Mill.) has encouraged its cultivation on a bigger scale. However, the species’ demand for nutrients and response to fertilization is not yet established. The aim of this study was to evaluate the effects of fertilization in agronomical, chemical and sensorial characteristics of Barbados gooseberry in a narrow row spacing and successive crops. The individuals have been cultivated without fertilization, and also with mineral and organic fertilizers, in a randomized block design with 7 replicates. Production analyses were carried out at 210, 270 and 330 days after transplanting (DAT), whereas mineral and protein contents were measured at 210 and 330 DAT and sensory analysis happened at 330 DAT. The mineral fertilization was more efficient to supply nutrients (P,K) and increase productivity.Fertilizers didn’t differ on their leaf protein content, chlorophyll concentrations and sensory characteristics.

    In this text I describe the application of the educational product carried out for the preparation of the dissertation of the MNPEF (National Professional Master's Degree in Physics Teaching). The developed product is a text material to guide the production of stop motion animations in the teaching of Physics. The work is based on the concept of perception proposed by Gestalt thinkers. One of the main representatives of Gestalt, Arnheim criticizes the exclusion of intuition in science education as opposed to an overvaluation of inductive logical reasoning. This work is inspired by this criticism to propose a method of visual creation that can be adopted by the teacher as an alternative for visual production that does not depend on computer programming skills typically used in making educational animations and simulators. The creation of stop motion can also be a tool for exercising intuition when produced by students. As for the application in the classroom, both possibilities were tested: video creation by the teacher using concepts of visual perception in the study of movements and the production of videos by students to exercise their perception and also to test the ease of execution of the procedures. guidance material.

    Exercise intolerance can affect upper limbs (upper limbs) and lower limbs (lower limbs) differently, with the upper limbs' muscle function being relatively preserved as they are more frequently used in routine activities of daily living (ADL), including personal hygiene or involvement of some of these muscles in breathing work. Despite the relative preservation of the function of the upper limbs muscles, it is common to complain of dyspnea on the part of patients with COPD when performing activities with the limb without support, that is, at or above the shoulders without support. One of the treatments indicated is endurance training, as for example on the arm cycle ergometer. The MMSS training in an arm cycle ergometer allows, by keeping the distal end of the limb supported, that the scapular waist musculature can assist in breathing, prolonging the duration of the exercise and delaying the onset of dyspnea. Despite the benefits such as improved exercise tolerance, quality of life and reduced dyspnea, this method has been passed over to training without support,. Patients with COPD and functional disability may have a greater tolerance for training without support when performing an adaptation period with the upper limbs training on a cycle ergometer, thus regaining their independence. However, there is difficulty regarding its use, since cycle ergometers with the necessary characteristics (measurement of load and cadence, and height adjustment) for the application of training with MMSS support are expensive and generally inaccessible to clinics and patients. Therefore, this study aims to propose a cycle ergometer adapted for upper limbs (article 1) and to verify the effects of its use on upper limbs training of COPD patients (article 2). To adapt the cycle ergometer of article 1, the Mini Bike PRO E13 from Acte Sports® was attached to a table with height adjustment plus a torque wrench on the right crank and a cadence sensor on the table. The study included the participation of patients of both genders, with a clinical and spirometric diagnosis of COPD who underwent an Incremental Exercise Test (IET) on the cycle ergometer adapted until exhaustion. Obtaining as results the evaluation of 13 individuals with COPD, (FEV1 / FVC: 0.50 ± 3.4), 67 ± 3 years, BMI 24 ± 4.14, irregularly active and active. The IET lasted an average of 9 minutes, reaching a maximum load of 4.5 N.m on average, with VO2max reached 0.80 ± 0.25 l/min, equivalent to 36 ± 12% of the predicted. We concluded that the equipment was able to assess the functional capacity when reproducing a submaximal IET in patients with COPD. In article 2, an experimental study was carried out, such as a randomized controlled clinical trial in a controlled block, blind evaluator and parallel group, using the MMSS cycle ergometer adapted in article 1. The training protocol lasted a total of 8 weeks, three times a week, 50 minutes each session. Patients were divided into Intervention (IG) and Control (CG) groups. Both started the sessions with stretching of the main muscle groups, followed by heating for three minutes with no load on the MMSS cycle ergometer at a 70 rpm without load. In the IG, they performed another 30 minutes with a load of 70% of the work rate found in the incremental upper limb test and ended with three minutes of cooling down without load. In the CG, all training on the cycle ergometer was carried out without load. To test the exercise capacity, IET and constant load test (CLT) were performed, to verify the functional capacity, the six minute pegboard and ring test (6-PBRT) and the TGlittre were performed, and to verify the health-related quality of life Saint George Respiratory Questionnaire (SGRQ) is applied. The IG obtained better results after the intervention than the CG in the physical tests IET load (+0.91), IET VO2 (+0.20), CLT time (+ 3min), and only the IG reached the minimum important difference in the CLT (+1.75 min). Both groups reached the minimum important difference in Glittre (GC -38 sec; GI -30 sec). Despite not having found statistical relevance, the present study showed that MMSS training in the proposed adapted cycle ergometer tends to be effective in improving physical capacity and functional status.

    The gradual obtaining of prerogatives from the Federal Prosecution Service started in the dictatorial period and enshrined with the promulgation of the 1988 Constitution, points to a course of institutional strengthening. This development was accompanied by the national press, with articles portraying the protagonists of the debates in this context. This monograph aims to reconstruct this process from the news coverage, identifying actors in dispute, regarding the MPF's prerogatives, during the 1987/88 National Constituent Assembly. The theoretical approach starts from the Bourdieusian concept of the field to identify the narratives and forces in dispute. The methodology is based on document analysis based on three strategies: 1) analysis of news content published by the newspapers “O Estado de S. Paulo” and “Folha de S. Paulo”, between 1985 and 1988; 2) exploratory bibliography study that addresses the lobby carried out by the Federal Prosecution Service; and 3) documentary analysis of the preliminary draft approved by the Subcommittee of the Judiciary and the Federal Prosecution Service, as well as the articles referring to the MPF in the constitutional text promulgated in 1988. The media outlined a positive portrait in defense of an institution's prerogatives and attributions that it was beginning to emerge as a defender of society and that, therefore, constituted a substantial legal protection against the arbitrariness experienced in the regime of exception. There was a congruence between the content of the speeches conveyed by the news coverage, by the MPF, by the preliminary draft of the SPJMP and, in large part, by the constitutional text approved in 1988.

    This paper presents a qualitative research in the field of Education, focusing on literacy skills in the modality of rural education, specifically that literacy, as a teaching and learning process, offered to students living in agrarian reform settlements and other peasant communities that practice family agriculture, seeking to verify the contributions of research based on dialogical learning to this theme. This is a bibliographical study, dedicated to the analysis of articles gathered from international scientific indexing databases, with the objective of verifying, analyzing, characterizing, and categorizing the contributions of theories and practices that have, as one of their theoretical foundations, the dialogical learning perspective, especially Paulo Freire's studies on literacy skills in rural education. The research work sought to verify how dialogical education can collaborate to the development of school practices in literacy skills that better correspond to the educational needs of peasant populations. The data were analyzed using the techniques of Content Analysis and Communicative Methodology, with the theoretical input of Paulo Freire and other authors with a communicative base, that is, who take the dialogical perspective as a strategy to overcome inequalities, through critical and problematizing thinking, which is done in the social praxis and constitutes action and reflection in interaction. The research has shown that there is a consensus in the studies of rural education with dialogic foundation about the need to adopt teaching and learning methodologies in literacy skills of rural populations, which take into consideration the rural territorial identity, demonstrating that not paying attention to the specificities can generate exclusion, collaborating to the historical marginalization experienced by rural people. The studies also present a set of didactic and pedagogical indications that point to a specific methodology to literacy skills in rural contexts, in order to value and promote historically subjugated rural identities. It also shows the occurrence of two important subfields of international studies, “Place-based Education” and “Rural Literacies”, which were not found in the national sample set. Thus, this research intended to present contributions to the practice of teaching literacy skills in the modality of rural education, which can promote instrumental learning and critical consciousness and, thus, collaborate to the social sustainability of rural people and their territories, promoting the ethical commitment to help rural communities to think about their demands, problems and, above all, their own social, economic, and cultural survival.
